ABSTRACT
QT/QS2 ratio has been assessed in 26 patients with both borderline and mild hypertension and mitral valve prolapse syndrome (19 patients), and hyperthyroidism (16 patients) in comparison with method control groups. The following polycardiographic parameters have been analyzed QT, QTp, QS2, QT/QS2, and QTp/QS2. Higher values of QT/QS2 ratio have been noted in patients with mitral valve prolapse syndrome and hyperthyroidism than that in the control group. There has been no difference in patients with mild hypertension while the values of the analyzed parameter have been significantly lower in patients with borderline hypertension. QT has been longer than QS2 (QT)QS2 1/in 9 (56%) patients with hyperthyroidism. A positive correlation between QT/QS2 ratio and ++thyroxine levels have been noted in these patients. QT values have been higher than QS2 values only in 1 patient with mild hypertension. It seems that QT/QS2 value has limited value as an indirect index of the adrenergic activity in the dysfunction of the autonomic nervous system.
